[Insight-users] unable to build itk without building zlib and png libs

[Luis Ibanez]

Hi Gaetan,

This is not a bug.

The option of using the system zlib, png... libraries has been removed.

The reason is that it became very hard to manage the cases where other
toolkits such as VTK and FLTK also linked to PNG and ZLIB libraries,
since you will have to ensure that they are all of the same version.

Applications using ITK+VTK+FLTK where having symbol collisions at link
time.

In the CVS version of ITK, we are using *only* the PNG, JPEG, TIFF and
ZLIB libraries distributed with ITK in the Utilities subdirectory. Now
the symbols of these libraries are ITK-mangled in order to avoid
conflicts when buildling applications using ITK and (VTK or FLTK).


Simply remove your entries for

       ITK_USE_SYSTEM_ZLIB ON
       ITK_USE_SYSTEM_PNG  ON

or set them to OFF.



    Regards,


       Luis
